F02D19/088 - CPC Classification

Classification description:

Controlling engines characterised by their use of non-liquid fuels, pluralities of fuels, or non-fuel substances added to the combustible mixtures peculiar to engines working with pluralities of fuels, e.g. alternatively with light and heavy fuel oil, other than engines indifferent to the fuel consumed simultaneously using pluralities of fuels; Premixed fuels, i.e. emulsions or blends; Control based on the fuel type or composition with determination of densities, viscosities, composition, concentration or mixture ratios of fuels by estimation, i.e. without using direct measurements of a corresponding sensor
